Sesión BGP no establecida cuando se usa la interfaz de bucle invertido

¡Hola!

Tengo un problema con mi configuración de BGP. Tengo dos enrutadores. Ambos utilizan MPLS y OSPF para la conectividad general. Se supone que ambos están conectados con iBGP en un VRF (Instancia VPN).

Quiero usar una interfaz de bucle invertido como la dirección de pares. Puse esos Loopbacks en el mismo VRF que la interfaz física. No funciona. Cuando uso las interfaces físicas como pares, funciona bien.

Eche un vistazo ... estoy hablando de la VPN "ACMS_Internet_Limited".
